3 Claims.

This invention relates to jigs used in making wedges for shoe heels and its primary object is to provide a jig by means of which these wedges may be very expeditiously and economically formed.

In the accompanying drawing in which like numerals designate corresponding parts:

Fig. 1 is a View partly in side elevation and partly in section of a jig constructed in accordance with the invention,

Fig. 2 is an underside plan view,

Fig. 3 is a rear end elevation, and

Fig. 4 is a side view of a collar, hereinafter described. l Y

Any suitable number of jigs may be employed to make wedges of varying sizes and there is a right and left hand jig for each size. Each jig comprises a base 5 and a cap plate 6, the two complementally forming a tong like structure adapted to grip and hold the stock 'I from which the wedge is formed. The tong-like effect is secured by pivotally uniting the base 5 and jaw 6 through the medium of a bolt 8 which is carried by the base and has a sufficiently loose t in the cap to permit the necessary slight rocking movement of the latter. A spring 9 bears between cap and base in advance of the bolt 8 and tends to lift the head I0, carried by the forward end of the cap. A toggle lock lever II is pivoted at I2 in the forked rear end of the cap and terminates in a cam-like tail I3 which thrusts against a fibre wear plate I4 carried by the base, when the hand grasp portion of the lock lever is thrust downwardly. At this time the tail I3 rides to past center position and holds the stock 1 in gripped position between head ID and the underlying front end Illa of the base. The base carries a lip I5 which limits the inward movement of the stock in positioning it and acts to hold the stock in place until it is gripped as well as during the shaping process. Rubber webs I6 of head I0 and II of the underlying part I Ila aid in forcibly gripping the Wedge stock 1. In addition, the engaging faces may be provided with prongs I8 which are forced into the stock and hold it against twisting with respect to the jig.

The underside of the base carries a guide plate I9 which may be Very hard fibre, leather, metal or any other suitable material and the configuration of this plate is that of the heel that is to be formed. Since the past center action of the lock lever II holds the jig shut, it follows that both hands of the operator are free to bodily manipulate the jig in guiding the plate I9 with respect 55 to the tool which shapes the rough stock 'I down to the configuration of the said plate.

A shaper table 20 and Shaper shaft 2l are shown in Fig. 4. A collar 22 is provided with a flange 23 which seats in a recess 24 in the table. The collar proper then acts as a guide for plate I9 and renders it unnecessary for said plate to ever come close enough to the Shaper shaft to be deformed thereby.

While the structure shown admirably serves the purposes intended it is to be understood that the invention is not limited to the precise construction set forth, but that it includes within itsv purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described our invention, what we claim 1. A jig comprising a pair of jaws consisting of a base jaw and a cap jaw, a wedge stock seat formed upon the base jaw at the forward end thereof, a guide plate of wear resistant material upon the base jaw beneath the wedge seat, an overhanging lip upon the base jaw at the rear end of the seat beneath which the wedge stock is adapted to engage and a lock for forcibly gripping and holding the stock upon said seat.

2. A structure as recited in claim 1 wherein the lock comprises, a lever having along arm and a short arm, the long arm lying along the cap jaw and the short arm being directed toward and acting against the base jaw and said lever being pivoted to the cap jaw at the juncture of its short and long arms.

3. A jig comprising a pair of substantially parallel jaws consisting of an elongated base jaw and a superimposed elongated cap jaw, a member loosely uniting said jaws at a point between their ends, a wedge stock seat formed upon the base jaw at the forward end thereof, a guide upon the base jaw beneath the wedge seat, a head upon the underside of the forward end of the cap jaw adapted to engage wedge stock seated upon the wedge stock seat, a lock llever having a long arm and a short arm, means pivoting the lock lever to the cap jaw at a point adjacent the rear end of the cap jaw, a wear resistant seat upon the base jaw against which the short arm of the lock lever acts, the long arm of the lock lever extending forwardly along the cap jaw, said cap jaw having an opening therethrough from top to bottomwithin which the lock lever lies.
